Scientific paper

The authors present an analysis deriving CNO abundances for two lithium-rich supergiants (HR 7008 and HD 174104). They also rederive lithium abundances using high-resolution, high signal-to-noise ratio Reticon data. They find that these stars do not have CNO abundances typical of other supergiants, that is, processed through the CN cycle, nor do they have the CNO content which would be expected if they were unprocessed stars. In HR 7008, ΣCNO is enhanced relative to iron; whereas, in HD 174104 ΣCNO is deficient relative to iron. There is no known scenario in stellar evolution which can explain these objects.
